A Detroit judge sentenced Alan Ralsky, a spam mastermind who headed an elaborate international organization, to 51 months in prison. Ralsky was convicted of wire fraud, mail fraud and violation of the CAN-SPAM act for his schemes.

Ralsky and his cohorts netted millions from pump and dump stock scams which were bolstered by their spamming. He pleaded guilty in June and will be serving time along with his son, who was sentenced to 40 months. [Ars Technica]
